3 Claims.

My invention relates to humidiers, particularly for use in connectionwith hot water or steam radiators in residences, oilices and all otherinteriors where it is desirable to increase the humidity in the airduring those periods in which the rooms are heated. My humidier also canbe used when the roo-ms arev not being heated, as in the summer time, toproduce a circulation of washed air.

It is well-known that in the heating of rooms and buildings,particularly in winter time and during extremely cold weather, thehumidity falls to a Very low point, often approaching complete dryness.This produces an atmospheric condiion at is injurious o w o worn an i tth t o d d urruture in the building, and also is not conducive to goodhealth conditions. Various means have been suggested for adding humidityto the air under such conditions, and my present invention has for one iof its objects to provide such means which may be connected with orinserted into the customary radiators using steam or hot water, andwhich, therefore, being embodied in the radiator itself, will not be inany way conspicuous and will operate with a high degree of efficiency,and which is economical to build and install.

The full objects and advantages or my invention will appear inconnection with the detailed description thereof, and the novel featuresof my inventive idea will be particularly pointed out in the claims.

[is illustrated, radiator sections are of the usual construction, havingupper and lower conhector nipples 11 and l2 of usual construction.

My invention is comprised in a casing 13 which may conveniently be oi awidth equal to two of the radiator sections 1G, and provided with upperand lower connector nipples 14 and 15, exactly the same as the connectornipples l1 and 12 scepting that they communicate with closed tubularpassageways 16 and 17 for conveying the steam through the system. Asclearly shown in Fig. 2,

" webs 18 and 19 divide the space within the casing 13 into two sidechambers 20 and 2l, and a central (C1, BSI-116) chamber 22. A water pipe23 passes along the upper steam line of the radiator and through theconnecting passageway 16, having branches 24 and 25 passing throughpackings in the Walls of said passageway 16 which terminate in spraynozzles 26 and 27 located at the top of the side chambers 20 and 21. Asshown in Fig. 1, two or more of my humidifying castings may be insertedin any particular radiator, and in such case the pipe 23 will becontinuous along the steam line so as to provide branch pipes for eachof the sets of side chambers of each humidifier section.

The side chambers 20 and 21 terminate in a top chamber 28 which isprovided with a perforated cover plate 29, as clearly shown in Figs. land 2, with raised portions 30 to make it match in appearance the top oithe radiator sections.

The water pipe 23 is connected with a supply pipe 31 having in it ashut-off valve 32 through a filter device 33 and feeds into nozzles 26and. 27 in a rotating manner not here claimed, delivering through acentral aperture of the nozzle, all in a well-known manner. The resultis sprays of water driven downward from the nozzles 26 and 27. As thespray is driven out under system pressure it will move at relativelyhigh speed and the particles of water will catch and carry with the airunder friction, drawing air through the perforations in the cover 29.

The bottom of each of chambers 20 and 21 extends into a semicircularpassageway 34 and 35 formed by lower semicrcular walls 36 and 37 and acentral casting 38 extending upwardly from the wall of steam passageway17. The semicircular passageway is further accentuated by thesemicircular cast segments 39 and 40, forming additional passagewaysystems 41 and 42. Both sets of passageways 34 and 41, and 35 and 42discharge upwardly into the bottom of the central chamber 22, and theair drawn down by the spray is forced upwardly in that way by thedeflector device thus provided. Here it enters a multiplicity ofpassages 43 and 44 which discharge through lateral openings 45 and 46through the walls of casing 10 into the space between the radiatorcoils, as clearly shown in Figs. 1, 2 and 3. The passageways 43 and 44with their connected lateral openings 45 and 46 are formed by curvedbarile plates 47 and 48, as best shown in Fig. 1. These baille plates,together with the curved bottom members 36, 37, 39 and 40 operate totrap and retain any free moisture from the spray, which descends throughslits 49 and 50 in partitions 39 and 40, and 51 and 52 in partitions 36and 37, and from there through drip openings 53 in the bottoms of thecasings 10, Where the water discharges to a drain pan 54 which, in turn,discharges through an opening 55 to drain pipe 56 leading to the sewer.

From the above description the operation of my humidifier will be clear.The water pipe running through the center of the main steam feed pipewill convey the water in a heated condition to the nozzles 26 and 27. Asthe spray is forced downwardly air is drawn through the openings in theperforated top member 29. This air, together with the spray strikes uponthe curved. bales 36, 37 and 39, 40 and is turned upwardly into thecentral chamber 22. There it enters the passageways 43 and 44, beingturned out into the space in the room next to hot radiator sections bybaie plates 47, 48 to emerge through the passageways 45, 46. During thewhole of this travel the air will be in contact with the water of thespray, and with water surfaces within the passageways, by which it willbecome saturated with Water vapor. At the same time, the action of thebaffle plates will be such as to cause deposit of all free water so thatthe saturated air discharges only with water vapor and without any freeWater.

The advantages of my invention will clearly appear in connection withthe detailed description heretofore given. Owing to the fact that it isapplied in one of the regular radiators, it is not unsightly orconspicuous, and its effectiveness is very greatly increased by reasonof the fact that the air is very considerably heated as it contacts withthe water vapor. While it is a primary purpose of the invention to applyit in and as a part of a hot water or steam radiator of any type orshape which may be used for heating rooms, it is practicable to use myinvention separate from such a radiator both for humidifying air and forwashing it when that may be desired. A further advantage of myconstruction is this: the humidifier sections may, and in practice will,be cast so as to correspond with one or more ordi- L94avce nary radiatorsections of the various types which are manufactured and installed, andwhich have been manufactured and installed. It follows, therefore, thatmy humidier may readily be inserted in the radiation of residences andother buildings already constructed and provided with steam or hot waterradiation.

I claim:

A humidier comprising a casing with means for inserting the same intoa steam or hot water radiator in communication with the upper and lowerconveyor lines for the heating medium, a water pipe extending throughsaid conveyor line and connecting with a nozzle within the chamber ofthe casing, and said nozzle spraying water through said chamber, andmeans for admitting air into said chamber adjacent said nozzle and forpermitting it to escape from said chamber at another point whereby theair is caused to be drawn into the chamber and expelled therefrom in amoistened condition.
